Distribution

Eurasian distribution from Japan to western Europe. Recently invasive in Great Britain.

Pest management

Monitoring

Pheromone-baited traps to monitor adults in summer.

Glue banding around trunks to monitor larval abundance.

Preventive measurements

Dendrolimus pini is favoured by monocultures of even-aged pine and by sandy freely draining soils. Mixing pines with deciduous tree species may lower the susceptibility of the stands.

Curative control

Aerial application of Bacillus thuringiensis is usually the preferred curative method.

Climate change

The effect of climate change on D. pini in Europe is unclear. Long-term measures in Poland showed that outbreaks are favoured by various climatic factors such as warm dry summers and cold winters, but these probably only affect the moth indirectly, through their effect on the host plant.
